Product Summary
The AY0438-I/P001 is a CMOS integrated device that drives a liquid crystal display, usually under microprocessor control. The part acts as a smart peripheral that drives up to 32 LCD segments. The AY0438-I/P001 needs only three control lines due to its serial input construction. The AY0438-I/P001 latches the data to be displayed and relieves the microprocessor from the task of generating the required waveforms. Applications are (1)Industrial displays; (2)Consumer product displays; (3)Telecom product displays; (4)Automotive dashboard displays.
